Imirasire mishya yizuba gusa yashyizeho amateka yisi kugirango ikore neza

Abahanga bakomeje gusunikaimirasire y'izubakugirango birusheho gukora neza, kandi hariho inyandiko nshya yo gutanga raporo: Ingirabuzimafatizo nshya yizuba igera kuri 39.5 ku ijana mugihe cyumucyo wizuba 1-izuba.
Ikimenyetso cyizuba 1 nuburyo busanzwe bwo gupima urumuri rwizuba rwateganijwe, ubu hafi 40% yimirasire irashobora guhinduka mumashanyarazi.Ibyanditswe byabanjirije ubu bwoko bwaimirasire y'izubaibikoresho byari 39.2%.
Hariho ubwoko bwinshi bwizuba ryizuba kurenza uko wabitekereza.Ubwoko bukoreshwa hano ni butatu-ihuza III-V tandem izuba, bikunze koherezwa mubyogajuru hamwe nicyogajuru, nubwo nabyo bifite imbaraga nyinshi kubutaka bukomeye.

Umuhanga mu bya fiziki Myles Steiner wo muri Laboratwari y'igihugu y’ingufu zisubirwamo yagize ati: "Ingirabuzimafatizo nshya zirakora neza kandi zoroshye mu gushushanya, kandi zishobora kuba ingirakamaro mu bikorwa bitandukanye bitandukanye, nk'ibisabwa cyane cyangwa ibyuka byoherezwa mu kirere.". ”NREL) muri Kolorado.
Kubijyanye no gukoresha imirasire y'izuba, igice cya "triple junction" igice cyo kuringaniza ni ngombwa.Buri ipfundo ryibanze mugice runaka cyizuba ryizuba, bivuze ko urumuri ruke rwatakaye kandi rukoreshwa.
Imikorere irusheho kunozwa hifashishijwe ikoranabuhanga ryitwa "quantum well" tekinoroji. Fizika iri inyuma yabo iragoye rwose, ariko igitekerezo rusange nuko ibikoresho byatoranijwe neza kandi bigashyirwa mubikorwa, kandi byoroshye nkibishoboka.Ibi bigira ingaruka kumyanya yumurongo, the umubare ntarengwa w'ingufu zisabwa kugirango ushimishe electron kandi wemere amashanyarazi gutemba.
Muri iki kibazo, amasangano atatu agizwe na gallium indium fosifide (GaInP), gallium arsenide (GaAs) hamwe na kwant yongeyeho neza, hamwe na gallium indium arsenide (GaInAs).
"Ikintu cy'ingenzi ni uko mu gihe GaAs ari ibikoresho byiza kandi bikunze gukoreshwa mu ngirabuzimafatizo nyinshi za III-V, ntabwo ifite umurongo nyawo w'utugingo ngengabuzima dutatu, bivuze ko gufotora hagati y'utugari dutatu Uburinganire ntabwo ari bwiza, ”Byavuzwe na NREL umuhanga mu bya fiziki Ryan France.
"Hano, twahinduye icyuho cya bande dukoresheje amariba ya kwant, mu gihe dukomeza ubwiza buhebuje bw'ibikoresho, butuma iki gikoresho ndetse n'ubundi buryo bushobora gukoreshwa."
Bimwe mubikorwa byongeweho muri iyi selile iheruka harimo kongera urumuri rwakiriwe nta gihombo cya voltage ihuye nacyo.Bindi bikoresho bya tekinike byakozwe kugirango hagabanuke imipaka.

Ubu ni bwo buryo bwo hejuru-izuba ryiza cyaneimirasire y'izubaselile yanditse, nubwo twabonye imikorere ihanitse ituruka kumirasire yizuba ikabije.Mu gihe bizatwara igihe kugirango tekinoloji ive muri laboratoire igere ku bicuruzwa nyirizina, ibishobora kunozwa birashimishije.
Ingirabuzimafatizo nazo zanditseho uburyo butangaje bwa 34.2 ku ijana, nicyo zigomba kugeraho mugihe zikoreshwa muri orbit.Uburemere bwazo no kurwanya imbaraga zingufu nyinshi bituma bikwiranye cyane niki gikorwa.
Abashakashatsi banditse mu mpapuro zabo basohora bati: "Kubera ko izo ari zo ngirabuzimafatizo zikomoka ku zuba zikoresha izuba 1 mu gihe cyo kwandika, utugingo ngengabuzima twashyizeho kandi urwego rushya kugira ngo bigerweho neza mu ikoranabuhanga rya Photovoltaque".
